Optical products, masters for making optical products, and methods for manufacturing master and optical products

摘要

The optical product may reproduce a first 3D image of at least a portion of the first 3D object and a second 3D image of at least a portion of the second 3D object. The optical product includes a first 3D image that when illuminated does not reproduce a second 3D image at a first angle of view and a second 3D image that does not reproduce the first 3D image at a second angle of view, And a surface configured to be reproduced by the recording medium. Each portion of the first portion corresponds to a point on a surface of the first 3D object and includes a first non-holographic feature configured to generate at least a portion of the first 3D image. Each portion of the second portion corresponds to a point on a surface of the second 3D object and includes a second non-holographic feature configured to generate at least a portion of the second 3D image.
